Desiccant is a dehumidifying agent which attracts moisture from the atmosphere. It adsorbs and holds particles of water to itself.  When desiccant becomes soiled or broken down over time, it becomes less effective. Inadequate desiccant can increase energy consumption via lower compression efficiency, air leakage, or pressure variability.

Sizing the Air Receiver

The effect of intake air on compressor performance should not be underestimated. Intake air that is contaminated or hot can impair compressor performance and result in excess energy and maintenance costs. If moisture, dust, or other contaminants are present in the intake air, such contaminants can build up on the internal components of the compressor, such as valves, impellers, rotors, and vanes. Such build-up can cause premature wear and reduce compressor capacity.

Condensation is the moisture that drops out of an air flow as it cools. The condensation in a compressed air system is a constant threat to cause expensive problems. The following are a few examples:

The standard drain for the air filter in an industrial compressed air system is a manual one, meaning that a maintenance person has to visit the location on a regular basis to ensure that free water and the “soup” of contamination that the filter strips from the air is drained before it can be entrained into the air stream.

At eCompressedair we can rebuild your tired and failing air ends to “like new” and some times “better than new status” in a mere 5 - 7 days. By rebuilding your air end, you can save up to 50% or more over the cost of a replacement. With 25 years of experience, we can provide an efficient and economical solution to your compressor’s poor performance using the original air end and its assorted parts.

A compressed air dryer is a device for removing water vapor from compressed air. Compressed air dryers are commonly found in a wide range of industrial and commercial facilities.

The term "desiccant dryer" refers to a broad class of dryers. Other terms commonly used are regenerative dryer and twin tower dryer, and to a lesser extent adsorption dryer.

A deliquescent dryer typically consists of a pressure vessel filled with a hygroscopic media that absorbs water vapor. The media gradually dissolves—or deliquesces—to form a solution at the base of the pressure vessel. The liquid must be regularly drained from the vessel and new media must be added. The media is usually in tablet or briquette form. (view Deliquescent Desiccant Tablets in stock)

Refrigeration dryers employ two heat exchangers, one for air-to-air and one for air to refrigeration. However, there is also a single heat exchanger that combines both functions. The compressors used in this type of dryer are usually of the hermetic type and the most common gas used is R-134a. The goal of having two heat exchangers is that the cold outgoing air cools down the hot incoming air and reduces the size of compressor required. At the same time the increase in the temperature of outgoing air prevents re-condensation.
